    Q
    Can Contrac Blox Rodenticide be stored in an unheated garage?
    A

    As a general rule we advise to store Contrac Blox Rodenticide and other rodenticides at room temperature, out of extreme heat or cold temperatures, to keep the product fresh. The food attractants in the bait will grow stale over time, making the bait less attractive to target rodents, so baits are …

    Q
    How long will Contrac bait stay fresh in plastic bag placed in bait box?
    A

    Once the container has been opened the Contrac has a shelf life for up to 1 year. If unopened the shelf life is up to 3 years. Bait placed inside bait stations should not be placed in plastic bags as this may deter rodents from consuming. Bait in bait stations should be replaced every 30 days or as …

    Q
    Will Contrac Blox work on squirrels? If so, how?
    Have squirrels in a wall-not sure of the entry point. How would I use this product to gt them to leave the wall?
    A

    Unfortunately Contrac Blox is only labeled for rodents like rats and mice.  Therefore we cannot recommend that it be used for ground squirrels.  We do not have any products that are labeled for squirrels specifically other than live catch traps.

    Q
    Will Contrac bait attract and kill moles?
    A

    We do not advise using Contrac Blox Rodenticide to treat for moles as it is not labeled to used for that treatment. Moles' primary food source is actually earthworms, and they stay underground to feed, so it is unlikely they would even consume a bait such as Contrac. Please refer to our guide o…

    Q
    Is there any secondary poisoning of chickens for Contrac Blox if they consume the rodents feces?
    I raise chickens and I am concerned about the rat turds left behind that can be consumed by chickens? Are the turds harmful to chickens? Its not their favorite food, but I do think they eat them sometimes. On a side note, I have the UV Contrac and, although not the primary intention, you can use a UV light to tell if you got it off your hands completely. I had to wash my hands 3 times before it was completely gone.
    A

    The chances of secondary poisoning by chickens consuming the feces left behind by rodents that consumed Contrac Blox is extremely slim. Normally animals have to consume multiple entire rodents in order to ingest enough poison to have any effects. Unless the chickens are getting direct access to the …

    Q
    Are chipmunks attracted to Contrac Blox Rodenticide?
    Already using traps for chipmunks but need more in the arsenal.
    A

    We cannot recommend that you use Contrac Blox Rodenticide or any other baits for chipmunk control since these products are not registered for that use. There are food attractants in any rodenticide that may be attractive to non-target animals, which is part of the reason these baits should be used i…

  • Asked by Johnny from Memphis, Tn.
    06/29/2016
    Q
    Is it safe (within the label and the law) to place Contrac blox above a drop ceiling in a restaurant?
    Is it within the label and the law to pop a few ceiling tiles out of a drop ceiling in a restaurant and scatter a few blox around for rats? I am aware that I would have to deal with the odor. I have been told that the blox must be secured in a station of some sort but the label says nothing about that.
    A

    By law Contrac Blox Rodenticide needs to be used inside a bait station, we would not recommend to toss loose blox in the drop ceiling. We would recommend using traps instead.

  • Asked by Mary from Texas
    07/20/2016
    Q
    Can I use Contrac Blox Rodenticide for rats in my attic?
    I have rats in the attic. Can I use this? Will they die in the attic and how likely is it that the rats actually live up there instead of just coming in every now and then?
    A

    We do not recommend baiting for rodents indoors as the bait can draw in insects. We would recommend snap traps or glueboards indoors. Rodents will go back and forth looking for food and harborage supplies. We recommend to also try and find out where they are entering and seal up those areas.

    A

    Contrac Blox Rodenticide and other similar products do have active ingredients that are toxic to fish, however secondary poisoning from a rodent that consumed the bait is generally only a concern with birds of prey or other scavengers that would actually eat the rodents who had consumed the bait.

  • Asked by Joe from Detroit Mi

    Q
    Could I use Contrac Blox instead of Terad3?
    I am looking for something that comes in an 18-lb. pail. There are pets in the area.
    A

    Contrac Blox would be a good option to replace the Terad3 blox. Be sure to continue using bait stations so that no non-target animals come in contact with it. Secondary poisoning is very minimal with Contrac and an antidote to the poison (vitamin K1) is readily available.

  • Asked by Douglas from Street, Maryland
    12/22/2016
    Q
    Is there a difference between "voles" and "meadow voles"?
    I'm confused since there is a discrepancy in the description of Contrac and in a question/answer from Mike in Caseyville, Il. In the description of Contrac it includes "meadow voles", yet in your response to Mike, you say to use Kaput. Which is preferred? We have been using Kaput and it is being eaten, but not sure of its effectiveness, since they seem to keep eating the bait. However, we may have a large infestation and it will take some time to eliminate all of them. Do you still recommend the Kaput over Contrac?
    A

    The question you are referring to may be outdated, so we will be sure to look into that.  Contrac previously was not labeled for voles at all, but the labeling has changed in the past couple of years to include meadow voles (the most common vole species) in addition to rats and mice.  Before this …

    Q
    Will Contrac Blox bait fit triangle stations?
    A

    We apologize, but the term "triangle stations" is a little vague.  We can tell you that the Contrac Blox are a standard size and will fit into most rodent bait stations, including triangle-shaped stations like the Protecta RTU Mouse Bait Station.

    Q
    How come the mice are not eating the Contrac Blox?
    I'm in pest control and have went back to this job numerous times they have no food laying around and there is no feeding on the contrac blox I'm stumped they won't even go for snap traps...
    A

    There are many reasons why rodents may not be attracted to a bait such as Contrac Blox. One very common reason is that the bait is not fresh; baits should be used within 1 year of opening, and stations should be changed every 30 days for the best acceptance. You should also be sure to wear gloves wh…

    Q
    If Contrac Blox have been placed within the root drip zone of pear and other fruit trees, is the fruit from these trees still safe for human consumption?
    A

    If the Contrac Blox have been used properly within bait stations, then there should be no concern about the bait contaminating any edibles. The anti-coagulant active ingredient in Contrac is not absorbed systemically into plants.

    Q
    I think my little dog may have licked one of the Contrac blox. Will this harm her?
    A

    Contrac Blox can be toxic to animals if enough is consumed, although an antidote, Vitamin K1 is readily available from your vet.  If you believe your pet consumed any amount of this product, it is important to contact your vet or pet poison control as soon as possible.

    Q
    Is Contrac toxic to opossums?
    I have a Bucket of Contrac that has been very effective with the rats. Recently, a possum has been breaking into the bait stations and stealing the bait. Will this harm the possum? This is a big problem for me because I have to clean up his crumbs so that other animals (chickens) don't get into them.
    A

    Contrac Blox Rodenticide is not labeled for possums but if they were to eat enough of it it could harm them.  It doesn't sound like your stations are secure at all to the ground or to some other structure.  You can use liquid nails and affix the station on a 1 x 1 foot paver you can buy from …
